DISK HARROW AND SEEDER.

SPECIFICATION formingpart of Letters Patent No. 470,363, dated March8,1892. Application filed August 3l, 1891. Serial No. 404,298. (Nomodel.)

To @ZZ whom, it may concern.-

Be it known that I, GEORGE W. PACKEE, a citizen of the United States,residing at Rock Falls, in the county of Whiteside and State ofIllinois, have invented certain new and useful Improvements inDisk-Harrow Seeders; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanyin g drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification. 4

My invention has reference to improvements in disk-barrow seeders; andit consists, irst, in mechanism for drivinga rotating seedshaft from theinner disk of each gang by means of friction-wheels adapted to havetheir tread on the convex side of said disks and lto be actuatedthereby; second, in means for adjusting said friction -wheels so as toequalize their speed in the different positions which the disk gangs mayassume; third, in the provision of a spring to regulate the degree oftraction upon the periphery of said friction-wheels; fourth, in certainimprovements in the Scrapers for said disks. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which Figurel is a side elevation, partly in section, of a machine embodying myinvention. Fig. 2 is a rear elevation of part of such machine. Fig. 3shows details of the construction and location of the Scrapers andscraper-bar. Fig. 4 is the same with reference to the aforesaidmechanism for driving the seed-shaft. Fig. 5 is a sectional view throughthe axle F and friction-wheels E E.

Similar letters and figures refer to similar parts throughout theseveral views.

A is the usual seed-hopper, suitably supported upon a frame slightly inadvance of the transverse draftplank B, to which the disk gangs C areattached pivotally in the usual way. Y

D D are the inner disks of each of the two gangs, which are of the usualconvex-concavo conformation. l

F. E are friction-wheels placed upon their common axle F and providedwith oblique faces conformable to the convex surface of the disks D,respectively. The disks D are rotated, of course, from and by theircontact with the earth, and this rotation is imparted to the axle F ofthe wheels E thro ugh the traction of the latter upon the disks D.

The axle F is journaled transverselyin the outer end of a frame 2, whichis hinged vertically at its inner end to any suitable part of themachine. On the axle F is centrally keyed a sprocket wheel G, from whicha sprocket-chain communicates rotation to a sprocket-wheel Il, seated onthe short shaft Il in front of the axle F and slightly below and in therear of the hopper A. On the axle H is rigidly seateda gear-wheel J,which eugages a similar gear-wheel K, seated on the shaft K', whichconstitutes the axle or shaft of the seed-discharge device. A verticalrod l is pivotally attached at its lower end. to the frame 2, near theouter end of the latter, and is adjustably suspended by being passedvertically through a plate 3, attached to the draft-plank B, and.partially supported on said plate by means of the helical spring 4,coiled around said rod between plate 3 and upper collar 8, the latterbeing adjustable on rod 1 by the set-screw 9. The spring shown on' rod 1below the plate 3 is separate and distinct from the spring 4, and saidspring below said plate is simply a cushion to relieve the upward jar ofthe friction-wheels E.

The advantage of driving the seeding mechanism from the inner side ofthe disk gangs is that there is thereby avoided the refuse of variouskinds which collects at the vouter end of the disk gangs. In use inconnection with throw-in harrows the axle F would be longer and thebevel on the wheels E on the inner side of the latter. In driving fromnear the periphery of the upper portion of the disk there is anadvantage over driving from the axle or from a sprocket-wheel seatedthereon in that the disk gangs in use are often sunk in the earth totheir axle, causing more or less interference with and sometimes abreakage of the driving-chain.

In order to equalize the velocity of the friction-wheels E through thevariant positions of the disk gangs in use,I provide at each end IOO 1or out in the end of the hub of the wheel E the space between saidwheels may be increased or lessened,in which event the tread of thewheel E will be moved radially to or from the axis of the disk D.

L is a scraper-bar suitably supported in ways from the disk-gang axleand adapted to be moved laterally by the lever M, fulcrumed on the beamB and having its actuating end engaging a vertical clutch N, formed onthe upper end of the arm O, the upper end of which projects upwardthrough a slot in the beam B, and by throwing the lever M completelyover laterally the barL is moved endwise to or from the disks. Slots areformed in the shoe P, in which the lever M is ful? crumed, (which shoeis fastened by vertical bolts 7 to the upper surface of the beam 13,)

and by means of said slots the shoe P mayv eral contact of each of theScrapers from the eccentricity of contour of the several disks and theimpracticability of spacing them precisely uniform makes it a necessitythat there shall be an individual flexibility on the adjustment of eachof the scrapers R. This I attain by lthe following construction: Thescraper R is seated pivotally under bar L by having its inner end formedinto a vertical sleeve T, held by an inner sleeve ll, provided withexternal annular flange l2 on its lower end, which flange extends undersleeve T and supports it loosely. Sleeve 1l is supported by its centralvertical bolt 13, passed downward through bar L and provided at itslower end with nut 14, which extends radially outward under sleeve 11.Scraper R is provided with upwardly-extending lug l5, adapted to abutagainst the rearside of bar L when said bar is at the limit of itsoutthrow and the cutting end of the scraper therefore not restingagainst disk D. A spring S, coiled around sleeve T and locked at one endbehind bar L and at the other end behind lug l5, holds lug l5 againstbar L when the Scrapers are thrown from the disks; but when the scrapersR are thrown toward the disks they engage the disks D before barL hasreached the limit of its instroke, and the last part of such instroketherefore withdraws lug l5 from bar L and the scrapers are held againstthe disks by the resultant compression of the spring S.

By obvious changes the wheels 'E can be placed on other of the disks,and by weighting the frame 2 one wheel E may be sufficient. What I claimas my invention, and desire to secure by Letters Patent of the UnitedStates,is A

l. In combination with the disk gangs C,

provided with concavo-convex disks D, a

frame 2, suitably hinged vertically at its forward end to the frame ofthe machine and projected backward above the inner ends of said diskgangs, friction-wheels E, suitably journaled in the rear end of saidframe and adapted to have their tread upon the inner disks of said gangson the upper portion of the convex side of said disks, and suitablemechanism for communicating the rotation of said friction-wheels to theseeding devices, substantially as shown, and for the purpose described.

2. In adisk-harrow seeder, the combination of a seed-discharging shaftin suitable relation to the seed-hopper, disk gangs, the frame 2,pivotally connected at its forward end to the harrow-frame and projectedto the rear and afljustably supported at or near its rear end, shaft F,transversely journaled in the rear-end of frame 2, sprocket-wheel G,seated on shaft F, beveled friction-wheels E, seated on said shaft andadapted to have their tread on the convex side of one of the disks, nearthe upper edge thereof, shaft I-l, journaled parallel with and slightlybelow the seed-discharging shaft, sprocket -wheel H, seated thereon, asuitable sprocket-chain connecting wheels G and H, gear-wheel J, seatedon shaft H', and gear-wheel K, seated on the seed-shaft aforesaid andadapted to be actuated and rotated by gear-wheel J, substantially asshown, and for the purpose described.

the ends of said shaft, and set-screws 5, seated in the outer ends ofthe hubs of Wheels E, with theinner ends of said set-screws bearing,respectively, against the ends of said shaft, whereby the intervalbetween wheels E can be varied to place the tread of said wheels to orfrom the center of said disks, substantially as shown.
